[QUOTE="EdLennon, post: 1392459, member: 18402"] Hi all, I need some insight on my son's MX bike. He son has a 2007 CRF150RB. Last time he was riding, there was some abnormal noise coming from what seemed to be the left (shifter) side of the engine around the cylinder. The ran normal, but I did not want to let him ride it fearing that something might come apart and create a big mess. I tore the top end off and the first thing that I saw that was abnormal was the cam chain tensioner (the actual black plastic thingie that the puts tension on the cam chain) was worn, like frayed and split. So I figured that is where the noise is most likely coming from. The piston, rings, valves all appeared to be in very good condition. My question is this: Do I have to split the cases to replace the cam chain tensioner? If so, what else should I do while I've got it apart? New cam chain? Thanks for any insight from you guys!
